We propose a new service discipline, called the RateControlled Static-Priority (RCSP) queueing discipline, that can provide throughput, delay, delay jitter, and loss free guarantees in a connection-oriented packet-switching network. Previously proposed solutions are based on either a time-framing strategy, or a sorted priority queue mechanism. Time-framing schemes suffer from the dependencies t...

In this paper, we consider a multicore real-time scheduling algorithm incorporating benefits of both fixed-priority and dynamic-priority disciplines. Specifically, the algorithm first assigns globally-effective priorities to real-time tasks statically, based on the well-known Rate-Monotonic scheduling policy. It may however change the task priorities at runtime, only when the tasks reach the ze...

Flow control is the dominant technique currently used in communication networks for preventing excess traffic from flooding the network, and for handling congestion. In ratebased flow control, transmission rates of sessions are adjusted in an end-to-end manner through a sequence of operations. In this work, we present a theory of max-min fair, ratebased flow control sensitive to priorities of d...

Wireless Multimedia Sensor Networks (WMSNs) are networks of wirelessly interconnected sensor nodes equipped with multimedia devices, such as cameras and microphones. Thus a WMSN will have the capability to transmit data, video audio streams, still images, scalar data from environment. Most applications WMSNs require delivery information certain level Quality Service (QoS). This is challenging t...

Future integrated services networks are expected to carry various types of traac including real-time packet video for which stringent quality of service (QoS) requirements must be met. In this paper, we propose a cell multiplexing scheme for providing real-time communication services in point-to-point ATM networks. Our scheme is simple enough to be used in high-speed ATM networks, yet reasonabl...

To support emerging real-time applications, high speed integrated services networks need to provide end-to-end performance guarantees on a per-connection basis in a networking environment. In addition to the issue of how to allocate resources to meet diverse QOS requirements in a single switch, resource management algorithms also need to account for the fact that traac may get burstier and burs...

For contents delivery systems such as video-ondemand service, an optimum design is presented to maximize the utility of the system with priority classes. The willingness-to-pay (WTP) is introduced for a measure of utility, and the optimum design is discussed to maximize the utility (revenue). For the system with two priority classes, the optimum condition is given in terms of the traffic load, ...
